Configuring mesh networking support

6. Click OK to return to either the LAN1 or LAN2 screen where updates to the Mesh STP
Configuration can be saved by clicking the Apply button.
7. Click Cancel to discard the changes made to the Mesh STP Configuration and return to the
LAN1 or LAN2 screen. Once the Mesh STP Configuration is defined, the access point’s radio
can be configured for base and/or client bridge support.
Configuring a WLAN for mesh networking support
Each access point comprising a particular mesh network is required to be a member of the same
WLAN. Therefore, each base bridge, client bridge or repeater within the mesh network must use the
same WLAN in order to share the same ESSID, radio designation, security policy, MU ACL and
Quality of Service policy. If intending to use the access point for mesh networking support, Brocade
recommends configuring at least one WLAN (of the 16 WLANs available) specifically for mesh
networking support.
To define the attributes of the WLAN shared by the members of the mesh network:
1. Select Network Configuration -> Wireless from the menu tree.
The Wireless Configuration screen displays with those existing WLANs displayed within the
table.
Priority Set the Priority as low as possible for a to force other devices
within the mesh network to defer to this client bridge as the bridge
defining the mesh configuration (commonly referred to as the
root). Brocade recommends assigning a Base Bridge AP with the
lowest bridge priority so it becomes the root in the STP. If a root
already exists, set the Bridge Priorities of new APs accordingly so
the root of the STP doesn't get altered. Each access point starts
with a default bridge priority of 63335.
Maximum Message age The Maximum Message age timer is used with the Message Age
timer. The Message Age timer is used to measure the age of the
received protocol information recorded for a port, and to ensure
the information is discarded when it exceeds the value set for the
Maximum Message age timer.
Hello Time The Hello Time is the time between each bridge protocol data unit
sent. This time is equal to 2 seconds (sec) by default, but you can
tune the time to be between 1 and 10 sec. If you drop the hello
time from 2 sec to 1 sec, you double the number of bridge protocol
data units sent/received by each bridge. The 802.1d specification
recommends the Hello Time be set to a value less than half of the
Max Message age value.
Forward Delay The Forward Delay is the time spent in the listening and learning
state. This time is equal to 15 sec by default, but you can tune the
time to be between 4 and 30 sec. The 802.1d specification
recommends the Forward Delay be set to a value greater than half
the Max Message age timeout value.
Forwarding Table
Ageout The Forwarding Table Parameter value defines the length of time
an entry will remain in the a bridge’s forwarding table before being
deleted due to lack of activity. If the entry replenishments a
destination generating continuous traffic, this timeout value will
never be invoked. However, if the destination becomes idle, the
timeout value represents the length of time that must be
exceeded before an entry is deleted from the forwarding table.
